The Mediterranean Diet (MeDiet) has been studied in more detail than any other eating plan in the world. Does it deliver its claims that it may be so far the best diet for heart disease prevention?
Thanks to Authority Nutrition, the article looks at the research from subgroups of participants from the PREMIDED Study that studies two types of Mediterranean Diets compared to a healthy low-fat diet.
This article is a long read but an excellent summary and is simply stated. If you don’t care for details, please read the Results and Conclusions. There is interesting information about consuming a Mediterranean type diet and its proposed benefits for heart disease prevention.
Here is a description of the entire study.
“The PREDIMED study was designed to assess the long-term effects of the MeDiet on incident CVD in men and women at high cardiovascular risk. PREDIMED is a multicenter, randomized, nutritional intervention trial for the primary prevention of CVD performed in Spain from 2003 to 2011. The study was funded by the official Spanish agency for scientific research, Instituto de Salud Carlos III, and food industries donated the key foods used in the study. Full details of the study protocol have been described previously (19). Candidates were selected from primary care facilities affiliated with 11 recruiting sites and were at high risk of CVD but had no clinical disease at enrollment. Criteria for recruitment were age of 55–80 y and the presence of diabetes or ≥3 risk factors (smoking, overweight or obesity, hypertension, dyslipidemia, and family history of early-onset CVD )(Fig. 1). Participants were randomly assigned into 1 of 3 interventions: 1) MeDiet supplemented with extra-virgin olive oil (EVOO); 2) MeDiet supplemented with nuts; and 3) control diet (advice on a low-fat diet). Thus, the 2 MeDiet interventions were high vegetable–fat dietary patterns.”
